Solution
1. Preparation
  • Ensure the vehicle is parked on a flat surface and in 'Park.'
  • Disconnect the 12V battery for safety if needed.
  • Gather necessary tools: OBD-II scanner (if needed), multimeter, and basic hand tools.
2. Update Software
  • Connect the vehicle to Wi-Fi.
  • Navigate to the software update section in the vehicle settings.
  • Download and install any available updates, following the on-screen instructions.
3. Inspect Accelerator Pedal Position Sensor
  • Remove the floor mat to access the accelerator pedal.
  • Disconnect the electrical connector from the accelerator pedal sensor.
  • Use a multimeter to test the resistance across the sensor terminals while pressing the pedal.
    • Expected resistance should vary smoothly from 0 to the maximum value.
  • If readings are inconsistent, replace the accelerator pedal assembly.
4. Check Battery State of Charge
  • Use the vehicle's interface to check the battery percentage.
  • If the charge is low (below 20%), connect the vehicle to a charger and allow it to recharge fully.
5. Inspect Brake Pedal Position Sensor
  • Locate the brake pedal position sensor, typically near the brake pedal assembly.
  • Ensure the sensor is securely connected and free from debris.
  • Test the sensor operation using a multimeter; replace if faulty.
6. Reboot Infotainment System
  • Press and hold both scroll wheels on the steering wheel until the screen goes black.
  • Release the scroll wheels and wait for the Tesla logo to appear, indicating a reboot.
  • Monitor throttle response after reboot.
